S'rasems, citizens of the United States, residing at the city of Three Rivers, county of St. Joseph, State of Michigan, have invent- 1 ed certain new and useful Improvements in Motor-Cars, specification. v

This invention relates to improvements in motor cars.

of which the following is a Our improvements are especially designed for and are applied by us to railway motor cars, such as is illustrated in the accompanying drawings, although certain features thereof are applicable for use in various other relations.

The main objects of our invention are: First, to provide an improved motor car which. is very simple in structure and opera tion so that it can be operated by unskilled workmen such as the .trackmen ordinarily employed on railways. Second, to provide an improved motor car which is very economical and sim la in structure, and is, at the same time, c ective and durable. Third, to rovide an improved motor car adapted to operated wlth equal facility in either direction. Fourth, to provide in a structure of the class described an improved hanger for the engine. Fifth, to provide in a structure of the class described an arrangement of parts whereby the traction wheel alga serves as a crankshaft and a timer s Further objects, and objects relating toappear in structural details will definitely the detailed description to follow.

tion b the evices and means described in the fo lowing specification.

The structure described constitutes one effective embodiment of our invention. Other embodiments would be those skilled in theart.

The invention is clearly defined and pointed out in the claims.

a A structure constitutin an effective and preferred embodiment o the features of our invention is clearly illustrated inthe accompan g draw' forming a part'of this epeci cation, in w "ch:

Figure 1 is-a sidg'elevation of a structure embodying the features of our inv ntlon.

We accomplish the objects of our invenreadily devised by :3 operating levers. The inner end of the seat .8 is supported on the seat while its outer end latform 10. The frame...pieces 3 and 410 the. body are arranged to form a rail about these.

Fig. 4 is an enlarged detail section, taken on a line correspondingto line 4-4 of Fig. 3, showing details of the timer. F" 5 is an enlarged detail vertical section, tialren on a line corresponding to line 55 of Fig. 6, showing the arrangement of the engines and the hangers therefor. Fig. '6 is a detail view, part ally 1n vertical. section, on a line 6-6 of'Flg. 5. Fig. 7 isa detail view, showing the arrangement of the actuating lever forthe brakes and the connectionstherefor to the brake actuating rock shaft, the movement of the parts bein indicated by dotted lines. Fig. 8 is an en arged detail section,

taken one line corresponding to line 88 s of Fig. 7. Fig.9 is a'detail vertical section showing the arrangement of the cut ofi switch and fuel cut-off.

In the drawings, similar reference characters refer to similar parts throughout the severalviews, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the car illustrated is especially designed as a work car for track repair men. The body of the car preferably consists of suitable-longitudinal sills 1 and cross sills 2. Resting on the cross sills 2 are body side pieces 3, at the ends, of

which are transverse pieces 4. The seat 5 is arranged longitudinally of the car so-that the occupants may sit on either side, sidewise of the car.

vThe seat is sup rted by the standards 6 secured to the b0 y frame. At each end of the seat is a rail 7. An operators.seat 8 is preferably provided the same being arranged atone side of the main seat 5 so that the operator can sit facing in either directioni according to the running of the car.v This seat is located in convement relation to the is supported b the standard 9. I On either si e of the main seat is a.

Wilma he on body, g d also; is"? inner walls of the platforms. At either end the car is preferablyprovided with hand rods 12 for convenience in lifting the car to and from the track.

The wheels 13 are mounted on axles, as 14, the bearings for the axles not being here illustrated. One of the axles is also adapted as a crank shaft for the engines 15.- A pair of engines of the two cycle type is provided in the structure, the same being,as. stated, directly connected to the axle which serves asa crank shaft therefor. The details of these engines are not here illustrated.

Crank casings 16 are provided, the same being connected to the engines so asto inclose the ends of the cylinders thereof.

These crank casings are mounted on the axle.

The structural details of the casings are not here illustrated as such details form no part of the present invention.

The engines are preferably supported so that they may have a slight lateral movement with the axle. This is preferably accomplished by providing a pair ofhanger rods 17, with which the hangers 18 of the cylinders and crank case are slidably engaged,see Figs. 5 and6. This permits the connecting of the-engines directly to the axle,-that is, the adaptation .of the axle as a crank shaft, and the parts are relieved of any strain arising from the thrust on the axle. The axle is also adapted to serve as a shaft for the timer, which is mounted thereon at one side of the crank casing,- see Figs. 3 and 4. This timer preferably consists of a contact member 19, which is mounted upon the shaft, preferably by means of the collar 20, which is secured to the shaft, as by means of the set screw 21, so that it revolves therewith.

The co-acting contact members are'preferably in the form of contact balls 22, arranged in holders 23, which holders are mounted in a body portion or support 24 adjustably mounted on the axle so that they.

can be adjusted thereon to regulate the timing of the spark. The contact balls 22 are held yieldingly in their engaging position by the springs 25. The holders 23 areinsulated by the 'sleeves26. See Fig. 4. The circuit wires 27 are connected to the timer by the binding posts 28. The body portions or sup- .port 24 is adjusted through the hand lever 29. This lever is connected by the link 30 to an arm of the double armed rock shaft 31, the other arm of the rock shaft being connected by the link 32 to the arm 33 on the timer body 24. 'By this arrangement of the parts, the support may be adjusted, as stated, to properly time the sparking. As the engines are of the two-cycle type they will drive the car in the direction in which they are started to rotate. The fiming'of the to the direction of movement of the car to accomplish the same results.

The engine throttle lever 34 is arranged in convenient position to be manipulated by the driver when occupying the seat 8. The

details of the connection of this throttle lever are not here illustrated, as they form no part of the present invention.

To protect battery and coil and to prevent tampering with or unauthorized use of the car, we preferably provide a box 35' in which the battery and coil are arranged, see Figs. 1 and 9. The box 35 is preferably arranged under the seat and is preferably provided with compartments for the battery, a tool box 40 and a compartment into which the fuel tank 41 projects. The box is provided with a cover 37 and a lock 39. Within the box is a cut-off switch 36 for the battery which can be manipulated only when the cover 37 is open. A cut-off valve 53 is provided for the fuel feed pipe 54, the cut-off valve 53 being located within the box. The

compartment in which the battery 55 is 10- cated'is preferably provided with a removable end 56 which can be removed only when the door is open. This removable end 56 is provided as a matter of convenience in making the connections to the coil. The connections for the feed pipe 54 to the car-.- bureter are not shown herein.

The operating switch 38 is arranged to be manipulated from the seat 8. The details of these switches, are, however, not illustrated as they form no part of the present invention. Y

When the car is left standing at the roadside, as section or work cars of this type frequently are, the switch 36 may be opened, the cut-off 53 closed and the cover 37 locked. It is then impossible for any one to put anything into the'gasolene tank, the closure 42 thereof being under the cover, or to draw the fuel therefrom, and it is also impossible to turn on the electric current, or to get access to the battery coil, or tools.

The car is preferably provided with a brake adapted to be actuated from an actuating lever 43 when the same is shifted in either direction from its normal or inoperative position, so that the brake mechanism can be actuated by the same relative movement of the lever when the car is movin in either direction, thus avoiding any likelihood of accident on account of the confusion of the driver resulting from a change in the direction of movement of the car.

The lever 43 is connected to the brake shoes 44- through the rock shaft 45, which is provided with an arm 46 to which the lever 43 is connected through a link 47, and with an arm 48 which is connected to the brake shoes by the links 49 and 50. The links 49 are pivoted to the brake shoes and arranged in oppositely disposed pairs. The link 50 is connected to the arm 48 and to the links 49, thereby making a toggle connection for the rock shaft to the brake shoes and'simultaneously actuating the pair of brake shoes. The link 47 is preferably adjustably connected to the lever 43 by providing a lurality of holes 51 for the connecting bolt 52. A spring 53 is preferably provided for returning the parts to their initial or inoperative posit-ion.

Our improved motor car is very simple and economical in structure and is, at the same time, very eflicient and satisfactory in use. The car can'be driven in either direction wit-h equal facility without the necessit for especial adjustment.

e have illustrated and described our improved car in the form which we have em-" odied it in practice. We are, however, aware that it can be considerably varied in structural details without departing from our invention, and we desire to be understood as not only claiming the structure illustrated in its s ecific form, but also claiming the invention broadly within-the scope of the appended claims.
